Question about polyline drawing

[Wakkaman]

Hi all,

 

I started this week with autocad and did some tutorials. I am trying to reproduce this garden in autocad, just for practice:

 

 

Most stuff i am able to do. But the only thing i really find difficult is the fluid forms you see below in the garden.

I am aware of the polyline functions, and i am able to do it with polyline/arc, but it's really not intuitive and rather difficult.

I am also aware of the polyline options curve or split fit, but that's really not precise at all.

 

Any suggestion how to this more easy?

 

(And i have also another problem, somehow when i use polyline i get these weird boxes when drawing, probably turned something on....?)

 

(srry for my broken english).

Your weird boxes might be due to having the system variable FILL turned off.

Re: fluid curves used for pathways.

 

You could bring an image into AutoCAD and do your best to trace over them with a polyline then use the Spline option of the Pedit command to approximate them. A better way would be to digitize them in (electronic tracing) but you probably do not have a digitizer hanging around. The method would be very similar to the first one I mentioned but your picks would be more precise and you could use short polyline segments to rough-out the curves before converting them to splines.

Hej ReMark,

 

Thnks for your reply.

 

i went to a website for system variable fill command: SYSVDLG

 

But the command doesn't work.

 

I use autocadLT.

[ReMark]

Try typing the word FILL at the command line. If the command is recognized then set it from Off to On.

[Wakkaman]

Thnks again for the quick reply's.

 

I did fill, and tried off and on to see what is happens. If i turn fill off i still have this box instead of a line, if i turn fill on it get's even worse, becease the boxes are like a hatch/filled.

[Wakkaman]

Immediately when you click a point and want to draw it's not a line but a box.

Did you do a Regen after making the change from Off to On?

[Wakkaman]

Did regen, doesn't help..

[ReMark]

Just out of curiousity what width are you using for your polylines?

[Wakkaman]

Man thnks, i am stupid....

 

That was the problem.

[Wakkaman]

Thnks for the help and advice .

[ReMark]

Made more than my share of stupid mistakes too. Live and learn.

 

You're entirely welcomed.

You could bring an image into AutoCAD and do your best to trace over them with a polyline then use the Spline option of the Pedit command to approximate them.

 

On a purely personal quest for understanding, could you please explain why you recommend the Spline option, when by doing that, the resultant curve pulls away from the pick points?

 

I would have used the Fit option, but I am willing to learn new techniques.

[ReMark]

My picks using the digitizer's puck are so close together by the time I back out of the drawing (I zoom in quite close) the difference between "fit curve" and "spline" is negligible. But I do concede your excellent point.

[rkent]

You might try the SPLINE command also.

[Wakkaman]

Thnks all for advice.

 

I used spline goes excellent.
